Background:
Peripheral nerve sheath tumors (PNST) on the basis of some features can be categorized as benign or malignant by ultrasonography (USG) and magnetic resonance imaging (MRI).
Case presentation:
We report a case of 28 years old male presented with a huge swelling in his right forearm. While the features of MRI directed the diagnosis towards neurofibroma (NF), some of the features of USG were in favor of malignant PNST (MPNST). Finally the histopathology (HP) and immunohistochemistry (IHC) features were found to be consistent with that of MPNST.
Conclusions:
This case is an example of additive value of USG over MRI in identification of MPNSTs that can be helpful for appropriate management.
